Indeed, many centers that have adopted the practice of blastocyst transfer in the last few years are concerned about an increasing number of patients whose embryos don't survive to the blastocyst stage in the lab.
In more than 100 IVF cycles, embryologists at Stanford were asked to pick out the two best embryos per patient on day 3 and then again on day 5 before blastocyst transfer.
Still, even with blastocyst transfer
, the rate of multiple gestations in in vitro fertilization (IVF) remains far higher than that seen in untreated women.
The incidence of monozygotic twinning after blastocyst transfer
is also significantly higher in this study than the 0.
The second group will use PGD in combination with blastocyst transfer
on day five.
We do not do blastocyst transfer
at Baylor, and if you compare our pregnancy rates and multiple gestation rates carefully with the blastocyst programs, there are basically no differences," said Dr.
What's more, many reproductive specialists have recently begun to utilize a new ART procedure called blastocyst transfer
, which has been shown to maintain successful pregnancy rates while reducing the risks of multiple births.
Women between 34 and 38 years can expect to have approximately half of the reproductive potential with IVF and blastocyst transfer
as women younger than 33, Dr.
No higher-order multiples occurred with blastocyst transfer
in a large study involving women undergoing in vitro fertilization, Dr.
They do not address the newer blastocyst transfer
procedure, in which embryos are transferred on day 5, allowing clinicians to more accurately predict which embryos have the best implantation potential, Dr.
TORONTO -- Evidence continues to mount that blastocyst transfer
may be the solution for reducing the rate of higher-order multiple gestations in women undergoing in vitro fertilization.
also can boost pregnancy rates in women who have failed to become pregnant after undergoing at least three traditional in vitro fertilization (IVF) procedures, reported investigators in a second study.
The number of embryos or blastocysts transferred in each cycle was captured, but embryo and blastocyst transfers
were not reported separately.
Multi-generational carcinogenesis from diethylstilbestrol investigated by blastocyst transfers
Much attention has been centered on blastocyst transfers
, the newest assisted reproductive technology available.
